This is pure underground fight anime from an era when that meant something: no tournament brackets, no power scaling, just two martial philosophies trying to destroy each other across generations. The setup is brutally simple, a grudge match that never ended, passed down like a blood debt, and every fight exists only to prove one style superior. You're watching revenge that tastes like legacy, where the son has to answer for his father's victory by fighting a man who never stopped burning.
A shadow war between martial arts styles rages on. Years past, Pro Wrestling and Nanshin Shadow Style clashed in an underground arena to determine which fighting form reigned supreme. Nanshin Shadow won, but the victory came at a cost. Now the Pro Wrestling champion has returned, consumed by a need for vengeance and determined to obliterate the style that defeated him all those years ago. Standing in his way is Kiichi, inheritor of Nanshin Shadow Style and son of the original victor. The weight of his lineage falls heavy on his shoulders. If Kiichi fails, his martial art disappears from history entirely, erased by a man who refuses to accept his loss. The stakes couldn't be higher: one young fighter against a legendary warrior fueled by years of rage. Kiichi must master his fighting style and discover what it truly means to be worthy of his family's legacy. Between intense combat sequences and high personal stakes, this OVA captures the brutal world where martial pride outweighs everything else.
